Ride Rating


The car is powered by a 2.0 Ford Duratec. A NC Miata flywheel, clutch, and transmission provides power to the mid 80s RX7 differential. GSXR 750 ITBs, a custom tube header, and a MS3X ECU running full sequential control the power. The brakes and half shafts are a mix of NA and NB Miata parts.

Nice work! I considered using a 2.3 or 2.5 duratec in my locost, but could not find much in the way of megasquirt base maps for any of the duratec 4s. Did you build your map from scratch?

For the most part. I was lucky enough to find several ignition tables that other people had shared and I devised my table based on those - that took a big piece of guess work out of the equation. It will take a little more dyno time to get the last few percent but it seems pretty good so far. Between the ECU's data logging and TunerStudio/MegaLogViewer, getting the VE values set up was pretty straight forward - it just took some driving and tweaking.
